At least a portion of the keys 410 of the keyboard have a light incident surface 411 and a light exit surface 412. When the light L is irradiated from the air onto the light incident surface 411 of the button 410, the button provided in this embodiment has a refractive effect. For example, the light ray L is incident on the light-emitting surface 411 via the route C-C' and is emitted from the light-emitting surface 412. Thereby, the button 410 assumes an illuminated state. In this embodiment, the angle between the light exiting surface 412 of the button 410 and the light incident surface 411 is greater than ninety degrees. Of course, the button 410 can also have other light-incident and light-emitting surfaces, and the light can be incident and emitted from other faces of the button 410 while traveling. In this embodiment, the top of the button 410 may further have a second engraving portion 413 shaped to input a character shape. As shown in FIG. 5, the second engraving portion 413 is, for example, an English letter 0, and the wall thickness of the English letter 〇 is smaller than the wall thickness of the button 410 201015603. In detail, as shown in Fig. 6, the second engraving portion 413 has a first wall thickness m, the button 410 has a second wall thickness H2, and the second wall thickness H2 is greater than the first wall thickness m. Thus, when light is emitted from the button 410, the second engraving portion 413 will be brighter than the other portions of the button 410. In the present embodiment, the English letter 〇 is obtained by laser engraving. Preferably, the second engraving portion 413 is engraved from the inside of the button. In this way, the surface of the button can be flattened and has a good touch. Of course, in other embodiments, the second engraving portion 413 can also be obtained by other methods. When light is emitted from the top of the second engraving portion 413, the English letter 〇 appears on the top. In this way, the user can clearly recognize the symbol on each button 41〇 to operate the button 41. Preferably, the English letter 〇 can also be coated with fluorescent material on the inner side of the button 410 to increase the keyboard. The aesthetics when illuminated can also make it easier for the user to distinguish the symbols on each keyboard when the button 410 is illuminated. The button 410 can also be coated with a layer of light lacquer to increase the aesthetics of the portable electronic device. In the present embodiment, the light-transmitting paint is applied only to the surface other than the light-incident surface 4U of the button 410 to make it easier for the light to enter the button 10. Of course, in other embodiments, a light transmissive lacquer can also be applied to each side of the button. FIG. 7 is a functional block diagram of the host shown in FIG. 1.

In other embodiments, the brightness sensing unit 360 can be a peripheral light sensor 12 201015603 ambient light sensor. The brightness sensing unit 360 can sense the ambient light to generate a sensed value. When the sensed value is less than a first preset value, for example, 401ux, the brightness sensing unit 360 sends a first setting signal S1' to the control unit 350', and the control unit 350' makes the first setting signal S1'. The light emitting element 600 emits light. When the sensed value is greater than a second preset value, for example, 39001ux, the brightness sensing unit 360 sends a second setting signal S2' to the control unit 350', and the control unit 350' makes the second setting signal S2'. The illuminating element® 600 stops emitting light. Preferably, the brightness sensing unit 360 can issue different setting signals to cause the control unit 350' to control the size of the illumination of the light-emitting element 600. In other embodiments, the brightness sensing unit can also be a light sensing circuit having a light sensing element. The light sensing element is, for example, a photoresistor, a photodiode or a photonic crystal. FIG. 9 is a functional block diagram of another architecture of the host shown in FIG. 1. The mainframe 300 can also include a detecting unit 370 coupled to the control unit 350 ” for detecting one of the portable electronic devices 100.
